Physical Review D, 105(3) doi:10.1103/PhysRevD.105.0320062470-0010https://doi.org/10.1103/PhysRevD.105.032006https://hdl.handle.net/20.500.12713/2592Using an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb-1 collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we search for the baryon-number and lepton-number violating decays D0?p¯e+ and D0?pe-. No obvious signals are found with the current statistics. The upper limits on the branching fractions for D0?p¯e+ and D0?pe- are set to be 1.2×10-6 and 2.2×10-6 at 90% confidence level, respectively. © 2022 authors.
